3 Terms and definitions

The following terms and definitions defined in GB/T 14264 apply to this document. 3.1 Cadmium Zinc Telluride Single Crystal A solid solution alloy with a zinc blende structure can be regarded as a solid solution of cadmium telluride (CdTe) and zinc telluride (ZnTe); its molecular formula is Cd1-xZnxTe(0 \u003cx\u003c1),属于43m点群,F43m空间群。 Note. As the content x of the Zn component changes, its lattice constant also changes; it is mainly used for room temperature X-ray and γ-ray detectors, and mercury cadmium telluride thin The epitaxial substrate of the film. 3.2 Component x value The content of Zn component in cadmium zinc telluride single crystal can be regarded as the molar ratio of zinc telluride (ZnTe) to cadmium zinc telluride (CdZnTe). 3.3 Microprecipitation phase Affected by the temperature field distribution and segregation effect, the granular micro-precipitation phase of cadmium and tellurium may be formed during the growth of cadmium zinc telluride crystals. Not more than 100μm, which has a greater impact on the crystal quality. 3.4 Leakage current In the absence of radiation and high voltage, a stable current through the cadmium zinc telluride crystal. ......
